I’m offering background sync of images which works fine with a small number of images, but seems to stall once we reach 10± images that are being synced simultaneously (files are quite small, roughly 200k on a wifi connection).

This seems to only happen on iOS and I’m wondering if there’s some hard limit to the number of simultaneous requests I’m able to make with Ajax?

I realize there might be better ways of handling this, but I’m currently stuck with this solution
